Anybody know anything about these guys?

When I was doing the research on who was going to do my engine I never ran across these guys nor did any of my racing buddies mention them. All of that being said when you do have your engine built and I have my thoughts on that but you need to decide if you are going to run the spray from the onset. Otherwise, your engine will not have the life or the reliability you are seeking. I have had several discussions with Scott Shafiroff on this subject who is one of the foremost authorities on running “the spray”. The engine currently in my BH was not built for the spray and it was made to run on 93 pump gas, the heads and cam were ground to make a long flat TQ curve so that as we have but 1 speed to realistically run hard in the power is always present. Just some thoughts and you really should call Scott and tell him what you are thinking about because he would love to build a small block for our bikes and “get the word” out so to speak. The components he uses are absolutely the best obtainable and if you go to his website and look at the shop it looks more like a hospital than a engine shop because it is so clean.

There is a huge performance difference in the ability to use the horsepower from an automobile engine vs. an engine built specifically for the demands of a motorcycle esp. one with only 1 speed for running it hard.

My .02 hope it helps.

Lamont,

Looks like they have been around for awhile and they use good stuff internally, even on the "package" motors.

Regarding NOS, the new systems are not like the 'old days' where the fuel system had to be richened up in order to run the NOS....all of the modern systems introduce additional fuel along with the NOS to avoid detonation.
On the new systems, you can hit the button below WOT and not do damage, because the system is adding fuel as well. Try it on empty tanks and you will see how fast it will flood the motor.

You do have to be sure that the engine components are capable of the additional hp. For instance, GM does not recommend that a ZZ4 bottom end be continually subjected to over 500hp.....so it would be foolish to put a 200hp shot in a ZZ4 and not expect a problem somewhere. So if you were going to build an engine from the ground up, just make sure that the rods, pistons, etc. will handle the advertised hp plus any NOS that might warm your blood later on.......or simply plug a NOS system on to your current motor....remember the grin you got from the converter???? Double that with a shoot of the 'juice'.
And it's cheap :lol:
